View Controller Programming Guide for iOS 文档翻译

最近工作的任务不是很多，便有时间读读苹果的官方文档，于是便想要试着去翻译
一是希望能够提升自己英语的阅读能力；
二是通过苹果开发文档增进自己的技术水平
由于自己水平有限，此间有许多部分都是用百度翻译过来的

原文文档：

View controllers are the foundation of your app’s internal structure. Every app has at least one view controller, and most apps have several. Each view controller manages a portion of your app’s user interface as well as the interactions between that interface and the underlying data. View controllers also facilitate transitions between different parts of your user interface.
Because they play such an important role in your app, view controllers are at the center of almost everything you do. The UIViewController class defines the methods and properties for managing your views, handling events, transitioning from one view controller to another, and coordinating with other parts of your app. You subclassUIViewController (or one of its subclasses) and add the custom code you need to implement your app’s behavior

翻译：

试图控制器是你的app内部结构的，每个app都有至少一个师徒控制器，大部分的app拥有几个。每个试图控制器管理着部分app的用户界面以及界面和基础数据的相互作用。视图控制器还便于不同用户界面切换。
因为他们扮演着如此重要的角色，试图控制器几乎是你所做一切的中心。UIViewController类定义了方法和属性来管理你的视图，处理事件，从一个视图控制器过度到另一个视图控制器，还有协调你app的其他本分。你的基类UIviewController（或者它的子类）并添加应用程序行为所需的自定义代码
